A Door

The photo above from 1979 shows a Lawrence Livermore National Laboratory employee opening what was thought to be the world’s heaviest hinged door. It was 44 tonnes with a thickness of 2.5 meters and width of 3.6 meters. A special bearing in the hinge allowed a single person to open or close the concrete-filled door.

However, according to the Guinness World of Records, the world’s heaviest door is in fact the radiation shield door in the National Institute for Fusion Science in Japan. It weighs 720 tonnes, is 11.73 m high, 11.4 m wide and 2m thick.

So, we may be able to make tetraneutrons:

Is this something we can use for spaceflight?

Let's suppose it's possible to make long term stable tetraneutron matter. Is there some way we could store it in some sort of containment trap?

If so, could it be used for some sort of cheap powerful fission drive? I'm thinking the fuel is cheap uranium 238 or thorium maybe combined with lithium deuteride. The tetraneutrons provide a burst of neutrons to "catalyze" fission ... the charged particles from the reaction are deflected by magnetic field for thrust.

Basically, I'm thinking something similar to anti-matter catalyzed fission, but with tetraneutron matter ... of some sort. Somehow?

Is this an idea that even makes sense?
